BRASILIA A Brazil central bank source said on Tuesday that Banco Original’s liquidity was solid, and that it had placed an analyst inside the bank to speed up obtaining answers to prosecutors’ questions about a corruption scandal involving JBS SA, whose controlling shareholders control the bank.

The source spoke on condition of anonymity as they were not authorized to discuss the situation. Market speculation about the health of Banco Original was stoked by news earlier on Tuesday that the central bank had sent the analyst to work inside it, prompting the bank to issue a statement denying any liquidity problems.
